A biologist is studying diseases in chimpanzees. He takes three random samples of the same size from a troop of 150 chimpanzees. One sample indicates that 3% of the chimpanzees are
hairless, another sample indicates that 5% are hairless, and a third sample indicates that 4% are
hairless. How many hairless chimpanzees should the biologist expect to find in the troop?

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

the answer is a and d
